:prop_tgt:`AUTOMOC` enabled targets need to know the Qt major and minor
version they're working with. The major version usually is provided by the
``INTERFACE_QT_MAJOR_VERSION`` property of the ``Qt[45]Core`` library,
``INTERFACE_QT_MAJOR_VERSION`` property of the ``Qt[456]Core`` library,
that the target links to. To find the minor version, CMake builds a list of
available Qt versions from
- ``Qt6Core_VERSION_MAJOR`` and ``Qt6Core_VERSION_MINOR`` variables
(usually set by ``find_package(Qt6...)``)
- ``Qt6Core_VERSION_MAJOR`` and ``Qt6Core_VERSION_MINOR`` directory properties

If ``INTERFACE_QT_MAJOR_VERSION`` is not a valid number, the first
entry in the list is taken.
A ``find_package(Qt[45]...)`` call sets the ``QT/Qt5Core_VERSION_MAJOR/MINOR``
A ``find_package(Qt[456]...)`` call sets the ``QT/Qt[56]Core_VERSION_MAJOR/MINOR``
variables. If the call is in a different context than the
:command:`add_executable` or :command:`add_library` call, e.g. in a function,
then the version variables might not be available to the :prop_tgt:`AUTOMOC`
enabled target.
In that case the version variables can be forwarded from the
``find_package(Qt[45]...)`` calling context to the :command:`add_executable`
``find_package(Qt[456]...)`` calling context to the :command:`add_executable`
or :command:`add_library` calling context as directory properties.
The following Qt5 example demonstrates the procedure.
